Processing method for silver halide color photographic light-sensitive material

- Konica Corporation

A method used for processing a silver halide photographic light sensitive material including steps of developing and treating with a solution having bleaching capability. The solution having bleaching capability comprises a ferric complex salt of a compound represented by the following formula A: ##STR1## wherein A.sub.1, A.sub.2, A.sub.3 and A.sub.4 are independently a --CH.sub.2 OH group, a --PO.sub.3 M.sub.2 group or a --COOM group, which may be the same or different; M is a cation: and X is an alkylene group having 2 to 6 carbon atoms or a --(B.sub.1 O).sub.n --B.sub.2 -- group, in which is an integer of 1 to 8, B.sub.1 and B.sub.2 are independently an alkylene group having 1 to 5 carbon atoms, which may be the same or different. The solution can be used as a bleaching solution or bleach-fixing solution for color photographic material. The solution may further be used as a reducing solution for reducing an image formed on a photographic light-sensitive material.

Claims

1. A method of processing an exposed silver halide color photographic light-sensitive material comprising the steps of:

color developing the light-sensitive material with a color developing solution comprising a color developing agent, and
treating the light-sensitive material with a solution having a bleaching capability, after said color developing step, wherein
said solution having a bleaching capability comprises a ferric complex salt of a compound represented by the following formula A: ##STR27## wherein A.sub.1, A.sub.2, A.sub.3 and A.sub.4 are independently a --CH.sub.2 OH group, a --PO.sub.3 M.sub.2 group or a --COOM group, which may be the same or different; M is a cation; and X is an alkylene group having 2 to 6 carbon atoms or a --(B.sub.1 O).sub.n --B.sub.2 -- group, in which n is an integer of 1 to 8, and B.sub.1 and B.sub.2 are independently an alkylene group having 1 to 5 carbon atoms, which may be the same or different; provided that said compound represented by said formula A does not consist essentially of an optical isomer about the carbon atoms to which A.sub.1 and A.sub.3 are bonded.

2. The method of claim 1, wherein said solution having a bleaching capability is a bleaching solution to be used for bleaching a silver halide color photographic light-sensitive material.

3. The method of claim 2, wherein said bleaching solution contains said ferric complex salt in an amount of 0.05 to 2.0 mol per liter.

4. The method of claim 2, wherein said bleaching solution contains ammonium ions in a ratio of not more than 50 mol % of all cations contained in said bleaching solution.

5. The method of claim 1, wherein said solution having a bleaching capability is a bleach-fixer to be used for bleach-fixing a silver halide color photographic light-sensitive material.

6. The method of claim 5, wherein said bleach-fixer contains said ferric complex salt in an amount of 0.05 to 2.0 mol per liter.

7. The method of claim 5, wherein said bleach-fixer contains ammonium ions in a ratio of not more than 50 mol % of all cations contained in said bleach-fixing solution.

8. The method of claim 5, wherein said bleach-fixer further contains a compound represented by the following Formula FA; ##STR28## wherein R' and R" are each a hydrogen atom, an alkyl group, an aryl group, an aralkyl group or a heterocyclic group; and n' is an integer of 2 or 3.

9. The method of claim 8, wherein said bleach-fixer contains said compound of formula FA in an amount of 0.1 g to 200 g per liter.

10. The method of claim 1 wherein said solution having a bleaching capability further comprises a thiosulfate.

11. The method of claim 1, wherein said compound of formula A is selected from the group consisting of compounds of formulae A-1 through A-17 as shown below: ##STR29##

12. The method of claim 11, wherein said solution having a bleaching capability is a bleaching solution or a bleach-fixing solution to be used for bleaching or bleach-fixing a silver halide color photographic light-sensitive material.

13. The method of claim 12, wherein said solution having bleaching capability contains said ferric complex salt in an amount of 0.05 to 2.0 mol per liter.

14. The method of claim 13, wherein said bleaching solution contains ammonium ions in a ratio of not more than 50 mol % of all cations contained in said bleaching solution.

15. The method of claim 14 wherein said compound of formula A is said compound A-1, A-3 or A-14.

16. The method of claim 15 wherein said compound of formula A is present in an amount of 0.1 to 1.0 mol per liter.

17. The method of claim 13 wherein said compound of formula A is present in an amount of 0.1 to 1.0 mol per liter.

18. The method of claim 11, wherein said solution having bleaching capability contains said ferric complex salt in an amount of 0.05 to 2.0 mol per liter.

19. The method of claim 13, wherein the solution having bleaching capability is a bleach-fixer and further contains 0.1 to 200 g per liter of a compound represented by the following Formula FA;

20. The method of claim 19 wherein said solution having a bleaching capability further comprises a thiosulfate.

21. An aqueous processing solution for a silver halide color photographic light-sensitive material, said processing solution being a bleaching solution or a bleach-fixing solution which comprises a halide and a ferric complex salt of a compound represented by the Formula (A) ##STR31## wherein A.sub.1, A.sub.2, A.sub.3 and A.sub.4 are independently a --CH.sub.2 OH group, a --PO.sub.3 M.sub.2 group or a --COOM group, which may be the same or different; M is a cation; and X is an alkylene group having 2 to 6 carbon atoms or a --(B.sub.1 O).sub.n --B.sub.2 -- group, in which n is an integer of 1 to 8, and B.sub.1 and B.sub.2 are independently an alkylene group having 1 to 5 carbon atoms, which may be the same or different; provided that said compound represented by said formula A does not consist essentially of an optical isomer about the carbon atoms to which A.sub.1 and A.sub.3 are bonded.
